Laser Trip Wire With Breadboard Battery and Laser Supplies

Introduction: Laser Trip Wire With Breadboard Battery and Laser Supplies

Laser trip wire made with breadboard and laser.

On your door when someone walks in so they get scared. For robbers and criminals. My door doesn't have a lock so an alarm would be great for my door. After trying this with arduino the code was messed up so i found out a different way. this way was much simpler and actually worked. Some problems I had was the alarm and light would go on no matter what and the code for my origanal trip wire didn't work

Step 1:

Connect all the wires to the breadboard and the battery.

Step 2:

Aim the laser at the sensor and when you interfere with the laser the alarm will go off.
